hi all,
I have an hitachi's modem router based on a broadcom chip who is BCM6348,
I can't see any support of this in openwrt, freifunk ....
Many ISP use this chip on their modem-router and the firmware is opensource
the T-COM Speedport W 500V (clone of the hitachi AH4021), freebox (FR), fritzbox, livebox (FR) Siemens Adsl SL2-141-I .... have opensource firmware
They have many feature : an USB port (master or slave), 2 VOIP port, a braodcom minipci card (bcm 4318), 2 ethernet port.

i already worked on a port for this router but i stopped due the situation that many sources are missing in the gpl release. but there will be some ongoing process in future. i cannot open any details or time schedules. but a port is in progress _________________ one cigarette costs 2 minutes of your life.

thanks Brainslayer for you reply.
I am a noob in linux embedded system and there is my question:
Can i simply compile dd-wrt source for the broadcom 6348 without to mod the source?
where is the problem with this platform?
Can i change the TSOP flash chip with a bigger from a mp3 player?
it's a SAMSUNG K9F1G08U0A 128M x 8 Bit NAND Flash Memory.
It's possible
If pin 13 is conected on the board.. then i would think that you could use a mx29lv640at for a replacement flash ... 8M flash ---- and i dont think you can use one from a MP3 player ..
Iv looked around and i couldnt find it or a generic replacement at my more favorite supplyers here in the us ... i dont know of any overseas supplyers . _________________ WRT54G,GS v1.1, V2, V3 V4, V5

OK but i don't know where is the serial or Jtag connection (hitachi AH4021),
If you Have a device based on bcm6345 Bcm6348
Please say it here, when we are more, we can make a donation
my unit has a serial. and yours have too. i see it on the picture. the connector on the right top of the cpu is one. the jtag is something you have to search. but i dont have any jtag utility right now. the good thing. the cfe has a webinterface for debricking. just push the reset button 20 or 30 seconds and the webpage will appear on the default address _________________ one cigarette costs 2 minutes of your life.

I'm currently playing with this modem.
It's based on BCM9648.
Instead of applying directly an alternative firmware, I modify step by step the current version of my CI.Box.
Up to now, I rewrite in french hmtl pages and I suppress spaces in order to gain memory (webs directory is rebuced by 100K), I included a lot of function of busybox. And now i'm working about dhcp based on mac adress.
This is the welcome screnn by using serial interface

I'll be very happy if someone can tell me how to load ans start directly a firmware image with r command . The image will be located on an external tftp server.
I did a lot of tests and I don't understand which format must have my image.
I know how to write an image firmware in the flash then boot with it...but its very dangerous if my image is wrong specialy when I want play with cfe.
Thanks in advance.
I'm not sure this post is in the right place.
